Abstract
A method for measuring relative concentrations of materials in a mixture includes providing an emission coil and at least one reception coil, providing a mixture with n materials having different magnetic susceptibilities, and introducing the mixture into the reception coil. Using a voltage generator the emission coil is supplied with at least one nonzero excitation frequency so as to generate an excitation magnetic field and the signal of the voltage induced in the reception coil is measured. Relative concentrations of the n materials are determined based on comparison between the overall susceptibility of the mixture as obtained through the voltage measurement and that of a reference mixture for which the relative concentrations of the n materials are known.
